	The sample window manager "wm" in R2 does this in the file test.c
(under directory ..X.V11R2/core.src/demos/wm) by attempting to change the
window attributes of the root window. It indirectly determines this through
setting an errorStatus return in the resulting XError if there is already a 
window manager running. This is done in the file errHndlr.c in the same 
directory.

	I don't know how legit this is, but I guess it's one method!
